[Bug 427612] Re: kvm sends caps lock key up event twice

[Benjamin Drung]

Attached a new version of my patch. You find two branches linked to this
bug for maverick and natty. The patch sets SDL_DISABLE_LOCK_KEYS and get
rid of the complete workaround in qemu-kvm. This requires SDL >= 1.2.14.

Addressed by new patch.

Addressed by new patch.

Is this a regression of my patch or is it the case for the unpatched
qemu too?
